The Azure Network Engineer Associate certification validates the ability to design, implement, and maintain Azure networking infrastructure: hybrid connectivity (VPN, ExpressRoute), VNets, Azure Firewall, Application Gateway, Load Balancer, Front Door, traffic management (Traffic Manager, Route Tables), and private connectivity (Private Endpoints, Private Link).
This is the canonical Azure-networking specialty for network engineers, cloud architects, and security professionals working with Azure-hosted workloads.
